### 4/5 — Wonderful tones and impressive interface. Confusing stop names.

*2026-01-27*

I wish the names of the stops were given in full as opposed to their abbreviations. It’s clearly an app intended for those that know what they’re doing. I am not one of those people and the app in that regard isn’t hugely helpful. It certainly doesn’t hold your hand. But I guess that’s not the target audience, which is fair enough. Thank you for making this app though, very cool and very impressive.

### 4/5 — Muito bom

*2026-01-24*

Ótima interface, ótimos timbres! Senti falta apenas de mapeamento MIDI pra acionar os registros. No geral, é um excelente app para organistas!

### 1/5 — Cannot choose any stops.

*2023-12-17*

When I touched the organ console, it didn’t show any stops because of a glitch that made it impossible to choose any stops. It happened days ago!

### 2/5 — Can’t tweak

*2023-12-01*

Locks up when I go to the stops page no visible controls just a blank cabinet on iPad Pro M1 chip  I use it sparingly and sounds great but wish I could build my own  presets
